Description
Technical field
The utility model relates to plunger connection component fields, and in particular to a kind of plunger linking combination.
Background technique
Plunger pump is an important device of hydraulic system.It is moved back and forth in cylinder body by plunger, makes seal operation
The volume of cavity changes to realize oil suction, pressure oil.Plunger pump high, compact-sized, high-efficient and flow with rated pressure
The advantages that easy to adjust.The occasion that plunger pump is widely used in high pressure, big flow and flow need to adjust, such as hydraulic press,
In engineering machinery and ship.
Plunger pump is divided into the axial plunger pump and radial plunger pump of two kinds of representational structure types；Due to radial plunger
Pump plunger pump belongs to a kind of efficient pump that novel technology content is relatively high, with the continuous quickening of production domesticization, radial plunger pump
The important component of plunger pump application field will necessarily be become；Radial plunger pump be piston or plunger vibration-direction with
The vertical plunger pump of drive shaft.Radial plunger pump working principle: driving torque passes to star by cross coupler by drive shaft
The hydraulic cylinder rotor of shape, stator is not by other horizontal forces.Rotor is on pintle.Radial arrangement in rotor
Plunger, be close to eccentric stroke stator by the piston shoes of static balance.Plunger is connected with slipper socket, and is locked by circlip
It is fixed.Piston shoes are stuck on stroke stator by two retaining rings.When pump rotation, it is pressed in by centrifugal force and hydraulic coupling due to inner surface
On.When the rotor is turning, due to the wobbler action scheduled, plunger will be reciprocating, its stroke is due to the 2 of eccentricity
Times.The eccentricity of stator can be adjusted by two opposite plungers of the radial position on the pump housing.The disengaging of oil liquid by the pump housing and
Runner on pintle, and controlled by inlet port on pintle, the hydraulic coupling generated in the pump housing is inhaled by the surface of static balance
It receives.The secondary static balance of friction takes overbalance pressure compensation method, forms opened loop control.Support the bearing of drive shaft only
It play supporting role, not by the effect of other external force.In hydraulic system: axial plunger pump is existed using the plunger parallel with transmission shaft
Volume caused by moving back and forth in plunger hole changes to work.Since the plunger and plunger hole of plunger pump are all round
Part, when processing, can achieve very high class fit.
Plunger directly passes through screw thread and is fastened directly to connecting portion in traditional structure, be easy to cause eccentric wear, plunger to it is related
Rigid unitary is formed after connector fastening, surplus is not adjusted in plunger.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of plunger linking combination is provided, this
Mechanism can avoid plunger eccentric wear to see automatic stop centering in fact while plunger piston locking.
To achieve the above object, the utility model is using following technical scheme: it include cushion block, disc spring, gland nut,
Positioning ring, plunger；Cushion block is arranged in connecting pin, and connector is caught in connecting pin by gland nut；Ring set is positioned on connector,
Disc spring is provided between positioning ring set and gland nut；Plunger is caught in inside connector.
The quantity of the disc spring is two.
Working principle of the utility model is: plunger is fixed to carry out automatic centering locking, dish by positioning ring and gland nut
Spring can generate certain rebound space to positioning ring, and plunger is made to possess certain adjustable surplus；Avoid plunger tight with related fittings
Gu rigid unitary is formed after, and deformation is caused to cause eccentric wear in continuous movement, reduces plunger service life.
After adopting the above technical scheme, the utility model has the beneficial effect that its is simple and practical, can automatically lock centering,
Possess adjustable surplus, avoid plunger eccentric wear, greatly improves its service life, and reduce accident rate.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Description of symbols contains cushion block 1, disc spring 2, gland nut 3, positioning ring 4, plunger 5.
Specific embodiment
Referring to shown in Fig. 1, present embodiment the technical solution adopted is that: it includes cushion block 1, disc spring 2, gland nut
3, positioning ring 4, plunger 5；Cushion block 1 is arranged inside connecting pin, and connector is caught in inside connecting pin to cushion block 1 by gland nut 3
Rear surface；4 sets of positioning ring on connector, 4 sets of positioning ring is provided with disc spring 2 with 3 inner space of gland nut；Plunger 5 is caught in
Inside connector.
The quantity of the disc spring 2 is two, and they oppose setting in 3 inside of gland nut.
Working principle of the utility model is: plunger is fixed to carry out automatic centering locking, dish by positioning ring and gland nut
Spring can generate certain rebound space to positioning ring, and plunger is made to possess certain adjustable surplus；Avoid plunger tight with related fittings
Gu rigid unitary is formed after, and deformation is caused to cause eccentric wear in continuous movement, reduces plunger service life.
After adopting the above technical scheme, the utility model has the beneficial effect that its is simple and practical, can automatically lock centering,
Possess adjustable surplus, avoid plunger eccentric wear, greatly improves its service life, and reduce accident rate.
The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple
The other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope should all cover in the scope of the claims of the utility model.
